SPECIFICATION forming part of Letters Patent N 0. 652,31 1, dated June26, 1900.

Application filed April 15 1899. Serial No. 713,124. (No model.)

To coll whom. it may concern.-

Be it known that I, JOHN T. HOURIHAN, of 1 Boston, county of Suffolk,and State of Mas- I sachusetts, have invented an Improvement inIce-Planing Machines, of which the following description, in connectionwith the accompanying drawings, is a specification, like letters andnumerals 011 the drawings representing like parts.

This invention relates to ice-planing ma chines; and it has for itsobject to improve the construction of the machine, to the end that alarge sheet of ice may be planed evenly and smoothly and to apredetermined level, the machine kept from sluing as it advances, theplaning-knife easily removed whenever desired for the purpose ofsharpening or otherwise and also adjusted to its support to compensatefor wear and also caused to occupy different elevations relative to therunners of the machine and also thrown up out of operative position toenable the machine to be transported, and, furthermore, to the end thatthe machine may be guided as it advances and its front end elevatedwhenever desired to raise the planing-knife free from contact with theice-as, for instance, when turning the machine-and, furthermore, to theend that the planed ice in rear of the machine may be cleared as themachine advances.

The machine comprises, essentially, a runner-bearing frame and aplaning-knife which extends from side to side of the machine; and theinvention consists, essentially, in mounting the planing-knife onmovable supports, whereby it may be thrown out of operative po-. sitionwhenever desired; also in holding said planing-knife rigidly inoperative position for use and for adjusting it to different elevationswhile so held; also in making the adjusting device, by means of whichthe planing-knife is held in operative position and in differentelevations relative to the runners, movable with the knife when thelatter is thrown up out of operative position;also inprovidingice-engaging guides in front and also at the rear of the planing-knifeat each end thereof, which are adjustable and mov-i able into and out ofengagement with the. ice, as may be required, said guides being employedfor the purpose of guiding the ma-j chine and also for assisting inpreventing the machine sluing as it advances; also in providing a frontshoe which is movable from a position above to a position below therunners, and vice versa, and which is adapted to be held fixed in eitherposition and when oc cupying a position below the runners will elevatethe front end of the machine, so that the planing-knife will be held outof contact with the ice, and also in providing means for clearing theplaned ice in rear of the machine, throwing the chips onto the unplanedice, and thereby obviating the necessity of going over the ice a secondtime with a specially-constructed apparatus for clearing the ice.

Figure 1 shows in plan View an ice-planing machine embodying thisinvention; Fig. 2, a diagram showing in full lines the ice as it willappear as the machine makes its first cut and the relative position ofthe runners and showingin dotted lines the position of the runners whenmaking the second cut. Fig. 3 is a longitudinal vertical section of themachine shown in Fig. 1, taken on the dotted lines a: m; Fig. 4., a sideview of the machine shown in Fig. 1; Fig. 5, a sectional detail of oneof the side bars of the frame and .runner carried by it; Fig. 6, asectional detail of one of the side bars of the frame and runner carriedby it, taken on the dotted line 2 .2; Figs. 7 and 8, details of theknife and its support; Fig. 9, a detail of one of the straps on thecross-bar for holding the adjusting-nuts in position; Fig. 10, a detailshowing one of the adjusting-nuts engaged by said strap; Fig. 11, a sideview of a portion of the draft-frame at the forward part of the machine;Fig. 12, a detail showing theclearing-board at the rear of the machine.Fig. 13 is a detail of the means for holding one end of theclearing-board ,in place.

The runner-bearing frame consists, essentially, of the side bars A A,arranged in parallelism and joined together by the cross-bars A A andbraces A Each side bar A A bears a runner Ct a, which is madeindependcut of the side bar bearing it, and said runners are connectedwith said side bars in an adjustable manner, whereby they may beindependently adjusted to different elevations. As a means of thusadjustably connecting the runners at a.

runners with said bars they may be pivoted thereto at their rear endsand their forward ends adjusted to different elevations.

As herein shown, a pair of vertically-disposed plates a are bolted orotherwise secured to the opposite sides of each side bar at or near itsrear end, and said plates project below the lower edges of the side barsand receive between themthe rear ends of the runners, and pivot-pins apass through the projecting ends of said plates and through the runners,to thereby pivotally connect the rear ends of the runners with the sidebars.

A pair of plates a similar to the plates 0. are secured to the oppositesides of each side bar A A at or near its forward end, the lower ends ofwhich project below the lower edges of the side bars and receive betweenthem the forward ends of the runners, although the projecting ends ofsaid plates are not connected with said runners, but merely serve toform vertical guides for the runners.

Adjusting devices are provided for the forward ends of the runners a a,by means of which they are held in different positions, and as hereinshown said adjusting devices consist of vertical screws a, passingthrough vertical holes in the side bars A A and projecting both aboveand below said side bars, and said screws turn in nuts a, (see dottedlines, Fig. 3,) which are set into and secured to the side bars alongtheir lower edges adjacent the runners. The lower projecting ends ofsaid; screws a pass freely through plates a which are secured to theupper edges of the runners, and beneath said plates recesses a? areformed, which receive heads a, formed or provided at the lowerextremities ofthe screws By means of said heads a and plates a thescrews a are connected with the forward ends of the runners and in amanner whereby said screws maybe revolved. Hand-cranks'a are attached tothe upper ends of said screws a 'gby means of which they may be turnedto raise and lower the forward ends of the runners. It is obvious thatany other form .or construction of adjusting device maybe provided foraccomplishing this result; but the form herein shown is simple andeffective and the runners not only adjusted to different elevatedpositions, but also held in whatever position they may be set. Therunners are thus supported by the frame and adjustable relativelythereto independently of each other.

A knife I), which is made as a flat blade or planing-knife, has itsfront edge beveled to serve'as a cutting or planing edge, and said knifeI) is made of suitable length to extend from side to side of the framebetween the The knife I) is attached to knife-supports b, which areherein shown as fiat arms pivotally connected at b to the lower ends ofvertically-disposed plates N, which are secured to the front side of thecross-bar A there being three such pivoted or swinging arms b supportedby said crossbar. These pivoted or swinging arms eitend forward and holdthe knife in proper position, as shown in Figs. 1 and 3, to plane theice. The knife is secured to the under side of the forward extremitiesof said swinging arms I) by bolts 2, which pass through transverse slots3, formed in said knife, and thence through the arms I), said slotsthereby enabling the knife to be adjusted back and forth in thedirection of the length of the slots. To more securely hold said knifeand better enable it to withstand the strain to which it is put whenplaning the ice, heelpieces b are bolted to the under side of theswinging arms, against which the rear or heel edge of the knife abuts,and said heel-pieces b are likewise formed with slots b for the bolts,whereby they may be adjusted to correspond to the adjustment of theknife. Plates 1) are secured to the upper sides of the extremities ofsaid swinging arms,which bear ears b and for simplicity of constructiansaid plates 12 are secured in position by the same bolts that are usedto attach the knife and the heel-pieces to said arms. Screwthreaded rodsb (three in number) are loosely connected at their lower ends to saidears U, and said rods are disposed vertically, or substantially so, andtheir threaded ends enter internally-screw-threaded nuts 5 which are setinto and supported byacross-bar c. The nuts 1) (see Fig. 10) havecylindrical bodies,

which enter correspondingly-shaped recesses,

in the cross-bar 0, being thereby free to turn in said recesses, andthey have at or near their upper ends circumferential grooves b whichoccupy a plane just above or flush with the top of the cross-bar c, andthe upper ends of said nuts, above the grooves, are formed asbevel-gears b. A pair. of straps Z9 (see Fig. 9) are provided for eachnut 19?, which are bent angularly to receive the crossbar 0, to whichthey are attached, and which abut together to embrace the nut, and saidstraps are formed with semicircular recesses 19 which when abuttingtogether receive the nut, and said semicircular recesses are made of asmaller diameter than the diameter of the recess in the cross-bar whichreceives the nut, and consequently the strap will project inward beyondthe walls of said recess. and will enter the circumferential groove b inthe nut b". The nut is thus supported by said straps, which enteritscircumferential groove, yet said nut is free to be revolved. Each nuthas at its upper end a bevel-gear 11 which is engaged byabevelgear I),secured to a horizontal rod or shaft b extending crosswise the machinein par- The threaded rods b and nuts 12 and the means employed forholding said nuts in position on the cross-bar and for operating saidnuts serve as and constitute means for holding the swinging arms I) andknife borne by them in operative position and also for adjusting saidknife to different elevations. As three swinging arms I) are hereinshown, I have also provided three threaded rods b nuts therefor, andmeans for holding and operating said nu ts,'all being mounted on thecrossbar 0. By turning the shaft h it will be seen that the knife willbe adjusted and held in different elevations relative to the runners andindependently thereof.

I do not desire to limit my invention to the particular construction ofthe means herein shown for holding and operating the adjusting-nuts or,in fact, to the particular means herein shown for holding the knife andadjusting it to different elevations, as it is obvious that other meansmay be employed by which substantially the same results may beaccomplished without departing from this invention.

When transporting the machine, it is desirable to raise the knife intoout-of-use position, whereby it cannot come in contact with anyobstacles, and as a simple way of carrying out this part of my inventionthe cross-bar c is made removable from the side bars A A bearing it andwhen removed may be swung rearward, as represented by dotted lines, Fig.3, the knife and its adjoining parts swinging on the axis of the armsI). The cross-bar c is herein represented as resting upon the side barsA A between blocks 0 c, which are secured to or which may form anintegral part of said side bars, and said cross-bar c is held inposition on said side bars by straps or plates d, which are pivotallyconnected to the blocks 0 at one end, as at d, and detachably connectedto the blocks 0' at the opposite ends by means of bolts (1 By detachingthe bolted ends of said straps cl they may be swung outward on theirpivots cl, to thereby permit the cross-bar c to be lifted from the sidebars and swung into the dotted-line position, Fig. 3, together with allthe parts attached to or borne by it.

The knife I) is normally held when in use so that it shall occupy aposition oblique to the plane of the tread-faces of the runners, asrepresented in the diagram, Fig. 2- -that is to say, one end of theknife will occupy a position substantially flush with the tread of onerunner, as a, and the opposite end of said knife will occupy a positionbelow the tread of the other runner, and such obliquity may be variedmore or less by the independent adjustment of the runners. The advantageof holding the knife in such relative position to the runners is thatwhen making the first cut, both runners bearing on the surface of theice, the cut will be slanting or oblique to the plane of the surface ofthe ice from side to side, and when making the second cut one of therunners will follow along in the deepest part of the first cut and theother runner will bear on the surface of the ice, and the said secondand successive cuts will consequently be in a horizontal plane.

In Fig. 2 the full lines represent the runners when making the first cutand the dotted lines represent the runners when making the second out.

A pair of vertical plates or bars c 6 (see sectional detail, Fig. 6) aresecured to the opposite sides of each side bar A A immediately inadvance of the knife I), the outside plate e projecting below the sidebars a short distance only and the inside plates projecting below theside bars and terminating with an ice-engaging prong c at a point belowor flush with the tread face of the runner. These plates 6 c on eachside bar serve to form vertical guides for the runners, and the insideplates having, as they do, an ice-engaging prong e will serve to engagethe ice just in front of the knife and may consequently be used inguiding the machine. The inside plates e are formed or provided withvertical slots 6 which receive the bolts by which they are secured tothe side bars, and said slots e permitvertical adjustment of the plates.

In rear of the knife I) an outside plate is secured to the outside ofeach side bar A A, and said platesfare constructed like the insideplates cthat is to say, they each have vertical slots which receive thebolts by means of which they are attached to the side bars and havetheir lower ends terminating in an ice-engaging prong at a point belowor flush with the tread-faces of the runners. Said plate may bevertically adjusted so that its ice-engaging prong may terminate aboveor below the tread of the runners. These rear plates f also serve asguides for the machine and also when in engagement with the ice willprevent the machine from sluing as it advances.

At the forward part of the machine a shoe 9 is provided, which ispivoted at g to a bracket on the cross-bar A and a hand-lever 9' isformed integral with or connected with said shoe 9, by means of which itis moved 011 its pivot. The shoe 9 may be moved to a position above orbelow the tread of the runners, and when below the tread of the runnersthe forward part of the machine will be slightly elevated in order thatthe planing-knife b may thereby be raised out of contact with the ice.In turning corners this shoe may be employed to elevate the forward endof the machine slightly instead of necessitating throwing up the knifeby the removal of the cross-bar c. The hand-lever g has on it aprojection 9 which is adapted to be engaged by a catch 9, pivoted at gto a stand on the frame and having a footpiece g for operating it, andsaid projection and shoe in its position to raise the forward end of themachine.

A cross-bar-h, formed with trunnions at the ends, is pivotally connectedwith the forward ends of the side bars A A, and said cross-bar has apole h attached to it. The pole h has a flat boardh placed upon it, andabove the board and also below the pole metallic straps 77/ are placed,and bolts pass through said straps, board, and pole to rigidly securethem together, thereby forming a rigid structure.

The straps h h one above and the other below the pole, both extendrearwardly beyond the pole for a short distance, and their extremitiesare bent at an angle, as represented in Fig. 3, and said projecting endsof the straps receive between them the pivoted bar h, and a bolt passesthrough said straps and also through any one of a series of holes h inthe bar h, to thereby connect the pole to said bar. At each side of thepole the board 7L2 has attached to it, above and below, a similar straph (see Figsl and 11,) and said straps extend rearwardly for a shortdistance and have their extremities bent at an angle to receive andembrace the pivoted bar h,although said projecting portions are notbolted to said bar. At the rear end of the machine a pair of handles "6may and preferably will be secured by means of a frame '5', which isattached to the rear ends of the side bars A A. Also at the rear end ofthe machine a clearing-board is provided, which is adapted to follow inthe rear of the machine and clear the cut of chips, and saidclearing-board is herein shown as a flat board n, set edge wise anddisposed obliquely to the travel of the machine, and on one side of saidboard nas, for instance, on its rear sidetwo pairs of ears n are shown,having vertical holes through them, the ears of each pair being disposedone above the other, and the uppermost ears are near the upper edge ofthe board and the lowermost ears are near the lower edge of the board.

An arm n is attached at n to the rear end of one of the side bars, whichprojects inwardly toward the clearing-board, and said arm is bentdownward at substantially right angles, and its downwardly-extendedportion passes through the pair of ears n at or near one end of theboard. This connection is, however, detachable for purposes to beexplained. An arm m is attached to the rear end of the other side bar,which extends rearwardly, and said arm m has a shortdownwardly-projecting pin m, which enters the uppermost car at theopposite end of the clearing-board, and said arm m is bent downward, asrepresented in Fig. 13, and its lower end enters the lowermost ear. Thisconnection is also detachable. The clearing-board will thus be securelyheld in an oblique position relative to the travel of the machine, withits forward end bearing against the side bar A and cross-bar A at thejunction of said bars, as shown in full lines, Fig. 1. Whenever it isdesired to reverse the position of said clearing-board n for the purposeof clearing the chips in the opposite way, it will be detached from thearms n and m. Then said arms will be detached from the side bars, andthe arm n will then be attached to the side bar A and the arm m will beattached to the side bar A and the clearing-board then placed in thedotted-line position shown in Fig. 1 and at tached to said arms.

The machine will be provided with a seat which will be supported by theframe in any suitable manner.
